Display device

Abstract

A display device is disclosed. A display device includes a connecting block ( 40 ) rotatably fastened to an end of a stand assembly ( 20 ); a head mount ( 43 ) vertically movable with respect to the connecting block ( 40 ); and a locking unit that selectively locks the motion of the head mount ( 43 ) as the connecting block ( 40 ) rotates.

1. A display device comprising:
 a connecting block rotatably fastened to an end of a stand assembly; 
 a head mount vertically movable with respect to the connecting block; 
 a locking unit that selectively locks motion of the head mount as the connecting block rotates, 
 wherein the locking unit includes a cam provided on a rotation shaft of the stand assembly, and a cam follower selectively locked to the head mount, being contacted with the cam, and 
 wherein the cam follower includes a first cam follower having an end contacted with the cam, and a second cam follower having a first end rotatably connected to the first cam follower and a second end selectively locked to the head mount. 
 
     
     
       2. The display device of  claim 1 , wherein the motion direction of the first cam follower is oblique to a motion direction of the second cam follower at a predetermined angle. 
     
     
       3. The display device of  claim 2 , further comprising a guide unit that guides the motion of the second cam follower. 
     
     
       4. The display device of  claim 3 , wherein the guide unit comprises a guide hole formed at the second cam follower and a guide pin provided in the guide hole. 
     
     
       5. The display device of  claim 4 , further comprising a guide bracket that guides the motion of the cam follower. 
     
     
       6. The display device of  claim 5 , wherein the guide pin is provided at the guide bracket. 
     
     
       7. The display device of  claim 1 , further comprising an elastic member that elastically supports the second cam follower. 
     
     
       8. The display device of  claim 1 , wherein a first engaging part is provided at the second cam follower and a second engaging part is provided at the head mount to be selectively engaged to the first engaging part. 
     
     
       9. The display device of  claim 8 , wherein the first engaging part and the second engaging part are rack gears, respectively. 
     
     
       10. The display device of  claim 1 , wherein a cam roller is provided at a lower end of the first cam follower. 
     
     
       11. The display device of  claim 1 , wherein the head mount and the cam follower are engaged with each other in a same direction as a rotation direction of the connecting block. 
     
     
       12. The display device of  claim 11 , further comprising a guide unit that guides the rotation of the cam follower. 
     
     
       13. The display device of  claim 12 , wherein the guide unit comprises a guide hole formed at the cam follower and a guide pin provided in the guide hole. 
     
     
       14. The display device of  claim 1 , wherein the locking unit comprises a motion part that moves in accordance with a rotation of the connecting block and a guide part that changes a motion direction of the motion part. 
     
     
       15. The display device of  claim 14 , wherein the motion part comprises a cam and at least one cam follower contacted with the cam. 
     
     
       16. The display device of  claim 14 , wherein the guide part comprises a guide hole formed on the motion part and a guide pin provided in the guide hole. 
     
     
       17. A display device comprising:
 a connecting block rotatably fastened to an end of a stand assembly; 
 a head mount vertically movable with respect to the connecting block; and 
 a locking unit selectively locks motion of the head mount as the connecting block rotates, 
 wherein the locking unit includes a motion part that moves in accordance with the rotation of the connecting block and a guide part that changes a motion direction of the motion part, 
 wherein the motion part includes a cam and at least one cam follower contacted with the cam, and 
 wherein the cam follower includes a first cam follower having an end contacted with the cam, and a second cam follower having a first end rotatably connected to the first cam follower and a second end selectively locked to the head mount. 
 
     
     
       18. The display device of  claim 17 , wherein the motion direction of the first cam follower is oblique to a motion direction of the second cam follower at a predetermined angle. 
     
     
       19. The display device of  claim 18 , further comprising a guide unit that guides the motion of the second cam follower. 
     
     
       20. The display device of  claim 19 , wherein the guide unit comprises a guide hole formed at the second cam follower and a guide pin provided in the guide hole.
